Hello,

I have a question regarding the VNAV path I can enter in the FMC:
 

What exactly is the benefit of entering the different heights for the waypoints here ?
In a similar FMC in the Majestic q400, for example, I have the possibility that the autopilot can follow the VNAV path exactly !
I don't see this possibility here in the Learjet ! Or have I overlooked something ?
So why should I enter a VNAV path at all ?

Please explain :-)
Maybe I'm just confused right now 😉

regards

LJ35 AP not have VNAV.

VNAV in FMC is just for info but this is good things also. Egg if ATC say: at waypoint XXXXX FL120, you just enter this altitude in this waypoint , select desired vertical speed in VNAV page and FMC will get to you distance to TOD, to be at this altitude at that waypoint.

Of course you can alone to calculate TOD based on ground speed, altitude etc but this is easier way, FMC calculate for you.

Thank you very much for your quick feedback :-)
Yes, this also confirms my assumption that the whole thing has a purely informative character !
